Abstract |
Data from several reaches of the lower Mississippi River, for a considerable range of discharge, are analyzed for the purpose of establishing a better understanding of the height of bed roughness and its variations along and across the stream. Data relating to the height of bed roughness in the channel, at crossings and at bends, yield to a quantitative solution. In this context, the channel is generally 'the deeper part' of the stream. Data relating to lateral variations in height of bed roughness are discussed in a qualitative manner. (Author) |
